It's about the angle, you cannot orient it towards your pads as much on a laptop.
I've convinced some if my girlfriends to switch as they have white versions and Blackwidows are fairly cheap on Ebay (£50-75). :) They like them as they're heavy writers.
I use softer keycaps, some are resin! I also have the back propped up like you mentioned with the built in lifts. I also have carpel tunnel so I don't want to cram my hands into a small space and it's OK to be slow sometimes. And a good wrist rest is key.
I've switched out keycaps to make them comfortable for me. You can customise them. I find it very hare to type on a laptop keyboard for a long time and it fucks up my posture.
It's not though. It's got advantages, but typing isn't one of them. I can open stuff peel based way better etc.
Actually, my giant mechanical Blackwidow keyboard is way easier to use than my laptop when my nails are long.
OK I'm not going crazy then.
